The largest part is this assembly is about ~50mm in diameter. These are fairly small parts so they should be able to fit on even the smallest of 3D printers. The parts are simple and doesn't require any support material. I suggest using standard PLA filament for these parts, as thats the most common and forgiving material.
The main pedant (Sheikah symbol) and outer bezel are 3D printed in two different colors. A 3D printer with a dual extrusion toolhead isn't required to achieve these parts. Instead, we can 3D print two colors by using a special pause option in our slicing software. Basically, we print the part in one color, pause the print at a specific layer, then change the filament, and resume printing. This "stacking" method is quite easy to achieve using slicing software like CURA and Simplify3D.
- 0-1mm for the base using black colored filament
- 1-2mm for the curvy features using gray colored filament
- 0-3mm for the base using translucent or white filament
- 3-4mm for the sheikah symbol using black filament
The parts were designed in Autodesk Fusion 360. If you're interested in modifying the parts, you can download the source file. If you're using different 3D modeling software, you can save it out as a STEP, IGS, OBJ and other file formats. The STLs can be downloaded "as is" from the repo sites listed below.
If you're looking to use the enclosure to house your GEMMA M0, you can download just the case parts. The case is a sub-assembly and available as a stand-alone download.
